What is Walt's mental disorder?

Walt has hypochondria. He worries about his health even after the doctor assures him repeatedly that he is okay.

Should we be concerned with his elevated blood pressure? Explain. (Look it up on the internet. What is an acceptable range?)

No. The acceptable range of blood pressure is 120/80 and 140/90, and thus Walt's blood pressure is very close to the normal one.

What is a diuretic?

A diuretic is a drug that that elevates the rate of urination and, through other mechanisms, lowers your blood pressure.

Treatment?

For treatment, he needs to exercise and eat healthier diet so that he is healthier and he also feels healthier. He should also have therapies with psychiatrists. It would be helpful for Walt to keep a journal to record his daily anxieties. Drugs such as fluoxetine, clomipramine, fluvoxamine, and imipramine may be given to Walt under the physician's advise.

Cognitive Behavioral Therapy
is effective in Walt's case, because it allows him to change his views with empirical support. After conducting experiments, he will recognize that his blood pressure is actually normal.
